I installed a water softener in a house we just moved into. I did a manual regen to test everything and nothing or at least very little drains past the P Trap and is pouring into the crawl space. I put a studor vent on the P Trap and have an air gap between the discharge hose of the softener and the p trap entry. The p trap is not clogged as it was just installed. Why is this not draining? What did I do wrong?(I know I'm using a pvc fitting on the air gap where it should be abs, this is the only thing that hasn't been glued yet, just haven't been to home depot to get the correct fitting and wanted to test it out first)

It was the slope, when cutting in the p trap I changed the slope of the existing 2" drain pipe, and caused it to back up. Re-did it and ensured the slope was correct and checked with a hose and a manual regen and all drains fine.
